OIL BURNER.

Application filed November 10, 1923. Serial No. 674,039.

To all whom it may concern.

Be it known that I, WILLIAM E. Knusn, a citizen of the United States, residing at Salina, in the county of Saline and State of Kansas, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

The present invention relates to oil burners, and the object is to provide an efficient burner for petroleum and heavy oils, which may be placed in an ordinary furnace, or similar device, without any considerable alteration in the stnucture thereof. A further object is to provide a burner of the character described which superheats its supply of air and introduces its supply of oil and air at the point of combustion in a novel and effective relationship for securing complete combustion.

A further object is to provide a device of the character described which is composed of few parts and is inexpensive to manufacture. I

In the accompanying drawings Figure 1 is a sectional view through a burner constructed in accordance with the present invention and installed in a furnace, the respective courses of the air and oil being indicated by arrows,

Figure 2 is a top plan View of the burner,

Figure 3 is a top plan view of the bowl of the burner,

Figure at is a top plan view of the oil vaporizer,

Figure 5 is a side elevation of the oil vaporizer.

In the embodiment disclosed, the side walls of a furnace are indicated at 6 and 7 and cemented therein,.as shown at 8 over the grate bars (not shown) is the burner, indicated generally by the numeral 9.

This burner comprises a bowl 10 having a flange 11 adapted to be mounted in the cement, as indicated in Figure 1, or upon any other suitable supporting means which seals the combustion chamber of the furnace from the ash compartment from below which the air supply for the burner is derived. Centrally located in the bottom of the bowl 10 is an opening 12 through which passes an oil supply pipe 13 leading from a suitable source of supply and having its delivery end 14 projecting upwardly within the bowl.

A vaporizer head 15 is disposed within the bowl 10, and comprises a base 16 carrying an upstanding boss 17 provided With an internally threaded recess 18 receiving therein the upstanding end 14 of the oil supply pipe 13; a reduced outlet passageway or nozzle 19 constitutes theoil outlet through the boss 17. Radial heating flanges or fins 20 are formed integral with the base 16 and boss 17, and have their outer ends extended upwardly.

Disposed diametrically over the bowl 10 is a double-arched supply conduit and heating chamber 21, preferably angular in cross section, and provided with inlet ends 22 and 23 located over openings 24 and 25 in opposite portions of the margin of the bowl 10, and thus opening below said bowl. The double conduit and chamber terminate in a common outlet nozzle 26 that depends centrally over but is spaced from the vaporizer and the vapor outlet 19.

In operation the oil is delivered through pipe 13, is vaporized in the part 15 and delivered to the point of ignition as indicated by the arrows on Figure 1. It is here commingled with the down-coming current of air and burned. It will be evident that the flame will be spread and contact the air chamber 21, thus preheating the air which is drawn from the chamber below the cornbustion chamber of the furnace. The parts are so disposed that the oil vapor and air are very thoroughly mixed, thus insuring complete and thorough mixture with resultant complete combustion.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim is 1. An oil burner comprising a burner bowl, a fuel vaporizer located therein and comprising an upstanding head having a vapor nozzle and provided on its outer sides with heat absorbing fins, and an air supply conduit overarching the bowl and having an inlet at the side thereof, said conduit having a discharge port over and in opposition to the head. 7

2. An oil burner comprising a burner bowl, a fuel vaporizer located substantially centrally therein and comprising a head up standing in the bowl and having an up.- Wardly discharging vapor nozzle, said head being provided on its outer sides with outstanding heat absorbing fins, and an air supply conduit overarching the bowl and having outer legs mounted on the margins thereof and opening through its rear side, said conduit having a central downturned 10 discharge opening above the vapor nozzle.

3. An oil burner comprising a burner bowl,- a ad ha ing a ase est ng in the bowl and an upstanding vapor nozzle, said nozzle having outstanding heat absorbing fins in the angle between it and the base, and an air supply conduit overhanging the bowl and having a downwardly directing discharge port over the head.

In testimony whereof, I afiix my signature.
